以上柴6135K-9a型柴油机为例,可将相关部件当作润滑油路的泄漏点。当一处的泄漏量发生变化时,机油压力就会改变。例如一台该型号柴油机在使用时出现气泵烧瓦故障。检查发现,该机通往气泵的机油节流孔堵塞,使气泵得不到润滑而烧瓦。如片面地扩大节流 The above diesel 6135K-9a diesel engine, for example, can be related components as a lubricant leak point. When a change in the amount of leakage, the oil pressure will change. For example, when a diesel engine of this model is in use, a pump failure occurs. Inspection found that the machine leading to the pump oil throttle clogged, so that the pump can not be lubricated and shredded. Such as one-sided expansion throttling
